Plumbogummite is a rare lead phosphate mineral with the chemical formula PbAl3(PO4)2(OH)5•(H2O). It forms in oxidation zones of lead deposits and primarily forms as a botryoidal mass after other minerals. The "plumbo" portion of this mineral's name is derived from the latin word for lead, "plumbum". "Gummi" comes from the gum like appearance that the mineral often displays.

Pyromorphite is a mineral species composed of lead chlorophosphate: Pb5(PO4)3Cl, sometimes occurring in sufficient abundance to be mined as an ore of lead. It forms small, hexagonal crystals ranging from dark green to yellow, to orange.

The lead in pyromorphite can be harmful if absorbed into the blood stream by inhalation or ingestion. The crystals won't pose a health hazard just sitting on a shelf but it would be recommended to wash your hands after handling.
